Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm running Ubuntu 6.06 on a Compaq Presario M2105US laptop. Sometimes, but not all the time, when I tell the computer to shutdown (via the graphical interface not the command line) it reboots instead. I can't see any errors or other questionable messages in dmesg. I don't really know what is causing it. If it happened every time it would be more easily trackable, but I can't figure out what needs to be done to recreate it; sometimes it happens, sometimes it doesn't.

Sorry, jeelliso, to post a "me, too!" entry, but I am having the same problem. I just upgraded to Ubuntu 6.06 and I can't shut it down. I've tried from the GUI's menu, from the login screen, and even trying to do a "/sbin/shutdown -h now" in console (non-GUI) mode.

I'm guessing there is a flag set somewhere, possibly as a "courtesy" to people who just installed the thing, but I thought I might try asking here, too, while I look through the configuration files.

Notes: Ubuntu 5.1 did not present this problem on the same machine: a Gateway G6-350, Pentium II. I used the upgrade manager to upgrade the distro.
